    摘要: There is provided a new antiviral antibiotic designated herein as BU-4724V which is produced by fermentation of a BU-4724V-producing strain of a new microorganism, Streptomyces sp. ATCC 55290. Antibiotic BU-4724V is recovered and purified from the fermentation broth by use of extraction and chromatography techniques. BU-4724V has been found to have some antibacterial activity and inhibits the growth of HIV and HSV viruses.
